Quantum Circuit Realization of the Bilinear Interpolation Method for GQIR

摘要

Quantum image scaling which is significant for advanced quantum image processing is the important branch of the quantum image processing. This paper proposes the quantum algorithm to scale up and scale down quantum images based on bilinear interpolation with integer scaling ratio. First of all the generalized quantum image representation which has been proposed is used to represent a quantum image with arbitrary size H x W. Then, the bilinear interpolation is used to create new pixels in the enlarged images. Based on them, the corresponding circuits of quantum image scaling algorithm are proposed.
